@EAM weima- Application led May'22, Serial los 562,8)58p To all whom, itmay eminem:

Be it known that I, Ronn'r VVARNOGK, al citizen of the United States,residing 1n Test Chester, county of Chester, and: State of Pennsylvania,have invented certain new` and usefulL Improvements 1n Cream Separators,of which the following is aspecifi cation. i

This invention relates to creaml separators and particularly totubular-separators of the general type shown in U. to HerbertMcCor-nacl'; llo. 795,360, dated- July 25, 1905. y

The general object of the invention is to'r provide a new and improvedseparator of the type above mentioned, rwhich will be simple 'inAconstruction, velficient in operatifon, and easily cleaned.

One ofthe features of the invention relates to an improved constructionand ar-z rangement of casing surrounding the bowl'.A

My improved bowl dividing wall and coupling structures are shown indetail in Figures 2, 3, fl, 5, 6, 7, and l0. At its bottom, the bowl isprovided with a bowl-bottoni of well known form adapted to be screwedinto the bowl. This bowlvbottom is provided with the usual boss havingan opening therethru, and with wings 5l which help to give the milkentering the bowl the rotary motion of the latter. At its upper end, thebowl 30 is provided with a converging portion to which is connected aneck 5l ot the form best shown in Figures 2, 3 and l0. The neck -l isprovided with skim milk openings 56 and 57, a vertical slot 58,partially circumferential and partially vertical slots 59, and withoppositely located llattened portions 61 and 62 adapted to receive awrench. The upper end of the neck 5l is machined so as to form acoupling face adapted to co-operate with a complementary coupling faceon the coupling member Gil which is preferably made integral with theend ofthe shaft 32 and is provided with wrench receiving surfaces 65 andThese coupling faces, when the bowl is in its op-' erative position, areheld in engagement with one another by a coupling bolt 69 located withinthe upper end of the neck 5l and co-olierating with a threaded hole inthe coupling member 64. The coupling bolt 69 is held within the neck 54by a pin 70 which passes thru said bolt and thru the slots 5f) in theopposite sides ot said neck, the ends of said pin 70 beingy secured in aring 7l movable on the outside of the neck The ring 7l covers the slots59 at all times, and said ring may be covered with an outside ring 72knurled on its outer suriace to facilitate moving it with the fingers.AThe bolt 69, in addition to serving as the means for drawing thecoupling faces into snug engagement, serves to hold in the neck 54, anew and improved form of dividing wall which will now be described, thebolt for this purpose being provided with a head 7 3 which may be ofmany different forms, one of which is best shown in Figures 6 and 7.

The structure of the dividingwall is best shown in Figures 2, l and 5.At its bottom, the dividing wall is provided with a cone shaped. portion75 adapted to conform to the converging portion 53 of the bowl 30; and.,above that `cone shaped portion is a cylindrical portion 76 adapted toslidingly it the interior of the neck 54 of the bowl. At its upper end,the cylindrical portion 76 of the dividing wall is provided with anopening 77 of the form best shown in Figure 5, adapted to receive thehead 73 of the bolt G9. It will be noted that the forni of the bolt-headas shown in Figure 7 and the liorm otl the opening 77 are such that,when the bolt-head is inserted in the opening and the bolt is rotated aquarter turn, the bolt-head will be in engagement with the llanged upperend of the dividing wall and will be capable of entering an upward pullon the latter. rl`he cone-shaped portion 75 ol2 the dividing wall isprovided with a plurality oit webs 79 which, as clearly shown in Figure2 act as spacers between the portion 75 of the dividing wall and theconverging portion 53 of the bowl 76. The cylindrical. portion of thedividing wall is provided with a lug 80 adapted to lill the slot 58 inthe bowl-neck 54 when the dividing` wall is inserted in the bowlneck.Located in a threaded hole thru the lug S() and the dividing` wall is acream screw 82 having an opening therethru communicating with the insideof the upper portion of the dividing wall. The dividing wall, bowl-neck,and coupling belt are so proportioned that when the dividing wall isinserted in the bowl-neck, it will be held therein by the coupling boltwhen the latter is moved to the position corresponding to the locationot the pin 70 in the upper end of the slot 5i), as shown in Figures 2and 2l. llt-nfl when the coupling bolt (il) in its upper position, it iscapable of beiig engaged by the threaded hole in the coupling member 6l.By applying wrenches to the wrench faces 6l--ll2 and (i5-mle, the bolt69 may be screwed into 'the coupling member -l until the coupling facesare drawn into snug engagement with one another; and it will be observedthat a clearance is lett between the bolt (if) and the inside of the endol the neck -l, so that the bolt is tree to adjust itsell and will actmerely as means tor drawing the coupling faces together, these facesbeing so :termed as to provide for proper alignment of the bowl 8O andthe driving shaft 32.

T he construction of the upper bearing 233 from which the shaft 82 issuspended is shown in Figures 8 and 9. This bearing, in some respects,resembles the bearing shown in McCornack patent hereinbefore mentioned.As in the construction ol'l that patent, the end of the shaft 232 isprovided with a cone bearing sleeve 85 secured against upwardlongitudinal movement on the shaft 32 by means of the screw Se, whichscrews into .the end of the shaft 32 and is provided with a head whichoverlaps .the .end et the shaft suiiciently to engage the end .of .the

bearing` 33, comprisesvvtwo.: nesting .cup-`v shaped portionsf90*and-9'1, which may be. riveted together;- at :their upper. flanged edgesas indicatedatI 9.2. These cup-.shapedl members: are adapted. to be'supported in the top.

The construction"` of my improved formvoli steadyingbearing is shown atthe. bottom of- FigureflO. The various partsfof thifs--bearF ing aresecured `toamouth-piece .100fhavin-g.y "a ilaringopemng therein and-1externally" threaded so as tobe capa-bleef screwing into a' threadedopening'in the bottomo the4 extension 26of1the-mainivframe ofi themachine.

lVith this construction-l of bearing, thebalbraee is` preventedrfrom.

By marking this' discreplaceable by other discs having holes oi? dif.- ferent sizes therein,it is possible 4tof use.` the other' parts of'y the steadying bearinginseparators having; widely differing capacities.. In order to provide fordrainage from the inside of the` steadying bearing, the slfiell'1101"Ais preferably provided with.' one or more openings 107 and theextension 26 is providedwith one or a plurality of openings Owing to thehigh rate of speed at whichy the shaft32', the coupling and the bowl..ro. tate', itis highly desirable that these parts be well protected.protecting means shown will now bede-r scribed. y

Referring to Figure 14, in the device therein shown, the bottom of thebowl casing 122 is provided with one or more angular slots 123 adaptedto co-operate with pins 124 in the extension 125 from the main frame ofthe machine, thereby providing a positive connection between the bowlcasing and the frame. In this construction, the arms 127 extending fromthe main frame and engaged by the bottom of the flange on the bowlcasing, are preferably smooth and not provided with any indentationssuch as those shown in Figure 12. The coupling guard 128 shown inFiggure 14 is the same as the coupling guard shown in Figure 12.
